Berliner Tageblatt - Former tennis world number 39 banned for doping

The former world number 39, who most recently helped coach current Australian players Chris O'Connell and Jordan Thompson, initially denied all charges.

But he admitted to blood doping in comments shortly before the hearing was scheduled to take place, the International Tennis Integrity Agency (ITIA) said.

An independent tribunal found he committed five anti-doping rule violations.

They included "use of a prohibited method through blood doping and facilitating another player to blood dope".

He also "provided advice to others on how to avoid positive tests, and use and possession of the prohibited substance clenbuterol".

Clenbuterol, a medication prescribed for treating asthma and other breathing difficulties, is sometimes misused by bodybuilders and athletes as an off-label performance enhancer.

Matosevic, who played at all four Grand Slams, is banned from any tennis event or activity authorised or sanctioned by the ITIA, such as ATP, WTA or Tennis Australia tournaments, until 2030.

The 40-year-old is likewise prohibited from coaching or working with any players.

There is no suggestion that O'Connell or Thompson have breached any rules.
